Abstract (en)
[origin: WO0187461A1] An adsorption/desorption unit (10) includes a hollow enclosure (12) containing one or more elongate hollow elements (16, 26) of activated carbon fiber cloth (ACFC) of appropriate length to cross sectional area to provide suitable electrical resistance for heating. The elements (16, 26) conduct electrical current to heat to a temperature that permits selective adsorption of a gas stream constituent and subsequent desorption to recover sorbate. Enclosure (12) houses ACFC elements (16, 26) and is arranged to direct gas stream flow through the elements and into and out of enclosure (12) via gas port (14, 30). The ability to heat the elements to a desired temperature by electrical current flow allows for straightforward implementation of selective adsorption. After an adsorption step, altering the temperature of the element or elements (16, 26) enables desorption. Enclosure (12) with the element (16, 26) also includes a liquid condensate outlet (38) and liquid sorbate is directly recovered as liquid from the same unit (10) used for adsorption and desorption.
